Adults aged 18 years and over: One to two tablets to be placed under the lip for a maximum of 2 days.Place the tablet high-up along the top gum under the upper lip either side of your mouth and allow it to dissolve slowly and completely. The tablet will soften and adhere to the gum, taking, for example, between 1 and 2 hours to dissolve completely.Most people find that after a few minutes they no longer notice the tablet. The tablet should not be moved about the mouth with the tongue as this will cause it to dissolve more quickly.If two tablets are required, the second tablet should be placed on the top gum adjacent to the firsttablet, but not on top of it. The tablet(s) is best taken after meals. Do not chew or swallow the tablet.If you wear dentures, the tablet(s) may be placed in any comfortable position between lip and gum.If you forget to take a dose it is not necessary to double the dose next time. Just carry on taking the medicine at the recommended dose.
